I have read all the note 8626084 & 890270
The above 2 numbers are not valid MOS docs (unless you mean patch numbers).
My problem is that i was dont know the easiest and simplest way to upgrade my application server.
Please follow the steps in (Upgrading to the Latest OracleAS 10g 10.1.3.x Patch Set in Oracle E-Business Suite Release 12 (Doc ID 454811.1)) to upgrade your 10.1.3 to the latest patchset level.
I sourced the env from the insttop, when i go my download location to start the ./runInstaller - it keeps failing no patches are applied.
You need to set your environment to 10.1.3 ORACLE_HOME as mentioned in the doc (Step 1 Set Your Environment to 10.1.3 ORACLE_HOME).
